Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 to 5, there is disclosed a divider that can fix both feet, comprising:

the gauge head comprises a gauge head 1, wherein a steel needle supporting leg 2 is arranged at the lower end of the gauge head 1, and a fixing plate 3 is connected to the outer side of the steel needle supporting leg 2; a fixed ruler 8 is arranged on the outer side of the steel needle supporting leg 2; the upper part of the gauge dividing head 1 is connected with a rotating shaft 14.

The gauge head comprises a connecting block 10, wherein the connecting block 10 is connected with the gauge head 1 through a sliding rod, a spring 15 is sleeved on the sliding rod, and a first gear 11 is arranged on the side part of the sliding rod; a second gear 12 connected with the steel needle supporting leg 2 is arranged in the connecting block 10;

the gauge head 1 is provided with a fixed block 17 for limiting the limit block 13 to move upwards and a sliding mechanism 16 for positioning downwards.

As shown in fig. 5, in the present embodiment, the sliding mechanism 16 includes a stop lever 161, a fixing lever 162, a return spring 163, and a stopper lever 164;

the reset spring 163 is arranged on the resisting rod 161 between the fixing rod 162 and the divider head 1, and the fixing rod 162 is arranged on the resisting rod 161 at one side far away from the reset spring 163; when the connecting block 10 is extruded downwards, the limiting block 13 is extruded to the resisting rod 161 until the resisting rod 161 is pressed by the reset spring 163 to be resisted on the limiting block 13 to limit the limiting block 13 to rebound upwards, so that the first gear 11 is meshed with the two second gears 12 to prevent rolling; when it is desired to lift up, the resist lever 161 is simply pulled to the left (as shown in fig. 5); the connecting block 10 is pulled back to the bottom of the fixing block 17 by the spring 15.

The lower end of the steel needle supporting leg 2 is provided with a steel needle 5; the outer side of the steel needle supporting leg 2 is connected with a screwing knob 4 of a fixed shaft 9, and the fixed plate 3 is connected with the steel needle supporting leg 2 through a threaded rod 7.

Two second gears 12 are arranged and are connected with the compass head 1 through a rotating shaft 6.

Fixed plate 3 is provided with two, and fixed plate 3 is about dividing 1 central line symmetry of gauge head, and fixed plate 3 is fixed connection with the connected mode of steel needle landing leg 2 simultaneously, can make fixed plate 3 fixed chi 8 to the reinforcing can also measure the distance between the steel needle 5 with fixed chi 8 to the fixed action of steel needle landing leg 2.

The connected mode of solid fixed ruler 8 and steel needle landing leg 2 is for dismantling the connection, and the half of the height that highly is less than fixed plate 3 of solid fixed ruler 8, and solid fixed ruler 8's length is greater than the length of steel needle landing leg 2 simultaneously, can make solid fixed ruler 8 conveniently dismantle to change.

The working principle is as follows: when using this divider who can fix both feet, at first, will examine the stability of the device earlier, then take corresponding operating position with this divider, then draw back the steel needle landing leg 2 of this divider, thereby convenient measurement, then push-and-pull connecting block 10 down, thereby make first gear 11 block second gear 12, thereby prevent steel needle landing leg 2 activity, then fix steel needle 5 in steel needle landing leg 2 through screwing up knob 4, then rotatory threaded rod 7, make fixed plate 3 not hard up, thereby the position of adjustment fixed ruler 8, then rethread threaded rod 7, make fixed ruler 8 fix, thereby improved the fixed action to steel needle landing leg 2, then use the divider through rotatory rotation axis 14, rethread fixed ruler 8 measures the distance between two steel needles 5.

If the distance between two steel needles 5 needs to be adjusted, the connecting block 10 can be pressed, because the inside of the gauge head 1 is provided with the spring 15 and the sliding mechanism 16, after the pressing, because the first gear 11 is connected with the connecting block 10 through the spring 15, the first gear 11 can move to the upper end through the spring 15, then the limiting block 13 can move to the lower side of the sliding mechanism 16, the sliding mechanism 16 can move to the lower side of the fixed block 17 through the extrusion of the limiting block 13, because the sliding mechanism 16 is inclined, and the spring 15 is further arranged at the tail end of the limiting block 13, the limiting block 13 can pass through the sliding mechanism 16 and the fixed block 17, because the expansion plate is arranged inside the spring connected with the limiting block 13, the spring connected with the limiting block 13 can be ensured not to move up and down, when the distance between the steel needle legs 2 needs to be adjusted, the first gear 11 needs to be lifted, at this time, the resisting rod 161 is pulled leftwards to make the resisting rod 161 contact with the fixed block 13, so that the first gear 11 is disengaged from the second gear 12, and the distance between the division legs can be adjusted, thus completing the whole working process, and the details which are not described in detail in this specification, such as the steel needle leg 2, the tightening knob 4, etc., are well known in the art by those skilled in the art.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
